60 yo/M patient presents with neck discomfort & LBP. No prior trauma, corticosteroid/opioId regimen or carcinoma is reported. AS has been diagnosed.
AP & LATERAL VIEWS OF LUMBAR SPINE.
Non-visualizaton of the SI joints is the first clue that AS is present.
The lateral view shows the classic syndesmophyte formation, discal calcification & nonvisualization of the posterior lumbar joints.
The lateral cervical spine views shows a small occipital exostosis, an arcuate foraman, spondylosis but importantly lower cervical syndesmophyte formation.
AS patient are at RISK for spinal fractures- 4x so. (1)These may subtle to detect & if SCI (spinal cord injury) is associated, a poor prognosis is associated. (2)
